Securely seals the ileocecal valve, between the colon and the small intestine. In the conventional sitting position, this valve is unsupported and often leaks during evacuation, contaminating the small intestine.

Relaxes the puborectalis muscle which normally chokes the rectum in order to maintain continence.

A highly effective, non-invasive treatment for hemorrhoids, as shown by published clinical research.

For pregnant women, squatting avoids pressure on the uterus when using the toilet. Daily squatting helps prepare one for a more natural delivery.

Historical Background

Man, like his fellow primates, has always used the squatting position for resting, working and performing bodily functions. Infants of every culture instinctively squat to relieve themselves.
Although it may seem strange to someone who has spent his entire life deprived of the experience, this is the way the human body was designed to function.

And this is the way our ancestors performed their bodily functions until the middle of the 19th century. Before that time, chair-like toilets had only been used by royalty and the disabled. But with the advent of indoor plumbing in the 1800's, the throne-like water closet was invented 22 to give ordinary people the same "dignity" previously reserved for kings and queens. The plumber and cabinet maker who designed it had no knowledge of human physiology  and sincerely believed that they were improving people's lives.

The new device symbolized the "progress" and "creativity" of western civilization. It showed that Man could "improve" on Nature and transcend the primitive cultural practices followed by the poor "benighted" natives in the colonies. The "White Man's Burden" typified the condescending Victorian attitude toward other races and cultures.

The British plumbing industry moved quickly to install indoor plumbing and water closets throughout the country. The great benefits of improved sanitation caused people to overlook a major ergonomic blunder: The sitting position makes elimination difficult and incomplete, and forces one to strain.

Those who could not overlook this drawback had to keep silent, because the subject was considered unmentionable. Furthermore, how could they criticize the "necessary" used by Queen Victoria herself? (Hers was gold-plated, befitting the self-styled "Empress of India.")

So, like the Emperors New Clothes, the water closet was tacitly accepted. It was a grudging acceptance, as evidenced by the popularity of "squatting stools" sold in the famous department store, Harrods of London. As shown below on the left, these footstools merely elevated one's feet in a crude attempt to imitate squatting.

The rest of Western Europe, as well as Australia and North America, did not want to appear less civilized than Great Britain, whose vast empire at the time made it the most powerful country on Earth. So, within a few decades, most of the industrialized world had adopted "The Emperor's New Throne."

150 years ago, no one could have predicted how this change would affect the health of the population. But today, many physicians blame the modern toilet for the high incidence of a number of serious ailments. Westernized countries have much higher rates of colon and pelvic disease, as illustrated by this report in the Israel Journal of Medical Science:

The prevalences of bowel diseases (hemorrhoids, appendicitis, polyps, ulcerative colitis, irritable bowel syndrome, diverticular disease, and colon cancer) are similar in South African whites and in populations of prosperous western countries. Among rural South African blacks with a traditional life style, these diseases are very uncommon or almost unknown.19

The following sections will examine these and other diseases in more detail to see how an unnatural toilet posture could produce such a wide range of harmful effects.

Pictures of ancient public toilets tend to confuse westerners, who assume that they were used in the sitting position. This impression is often reinforced by the pose of a comical tourist.

But, in reality, these are squat toilets.

They are elevated, not for sitting, but because there is an open sewer underneath. The cutouts in the vertical wall allow people to clean themselves with water, which is done from the front when squatting.

The ancient Romans used the posture shown below on the left. (Togas were more convenient than trousers, and provided some degree of privacy.)

The tourists shown below might be surprised to learn that, except for royalty and the disabled, everyone used the squatting position until the second half of the 19th century.22

Note: The Sulabh International Museum of Toilets website claims that archeologists have found "sitting-type" toilets at ancient sites, thousands of years old. The author of the site, Dr. Bindeswar Pathak, was asked for his evidence that these toilets were used in the sitting position. He replied that he actually has no evidence, but was simply repeating the assumptions of western archeologists.

In the diagram of the colon, please locate the cecum, the appendix and the ileocecal valve. The left side of the diagram corresponds to the right side of the body.

The cecum is a small pouch where the colon begins, in the lower right section of the abdomen. Wastes from the small intestine flow into the cecum through the ileocecal valve (theoretically a one-way valve.) The appendix is a narrow tube attached to the cecum, with a channel opening into the cecum.

Waste matter can get lodged in this channel, causing the appendix to become infected and inflamed. Immediate surgery must be performed to remove the appendix before it bursts. Otherwise, the result is usually fatal.

Why does the appendix get blocked with fecal matter? Did nature make a blunder in its design?

One clue comes from the field of epidemiology. Appendicitis is a disease of westernized countries, virtually unknown in the developing world.19,31 The reason is that the cecum was designed to be squeezed empty by the right thigh, in the squatting position. On a sitting toilet, it is physically impossible to compress the cecum.

Instead, one pushes downwards with the diaphragm, while holding one's breath. This maneuver inflates and pressurizes the cecum. It is analogous to squeezing a tube of toothpaste in the middle and causing the bottom of the tube to inflate. The pressure can easily force wastes into the appendix, with disastrous consequences.

The back-pressure can also overwhelm the ileocecal valve, whose purpose is to protect the small intestine from fecal contamination. Barium enema exams and intestinal surgeries routinely show the leakage of wastes into the small intestine. Crohn's Disease develops in the area soiled by this toxic backwash.

Despite all the straining, the cecum never gets evacuated. Residual wastes adhere to the colon wall, increasing the risk of cancer and inflammation (including appendicitis.)

By contrast, in the squatting posture, the right thigh squeezes the cecum from its base. Its contents are thoroughly expelled into the ascending colon, where peristalsis carries them away. There is no need to hold one's breath or push downwards, since the posture generates the pressure automatically.

The force is all directed upwards, so the appendix stays clean and the ileocecal valve stays closed. These organs were not "poorly designed"  as is currently taught in medical schools. Like the rest of the colon, they were designed with squatting in mind.

Historical Background of Appendicitis

Most people assume that appendicitis has always been with us. But in fact, it emerged quite recently, coinciding with the introduction of sitting toilets toward the end of the 19th century.22 According to the Medical Journal of Australia,

The epidemiology of appendicitis poses many unanswered questions. Almost unknown before the 18th century, there was a striking increase in its prevalence from the end of the 19th century, with features suggesting it is a side effect of modern Western life.30

In 1886, Reginald Heber Fitz, a Harvard Professor of Pathological Anatomy, became the first doctor to recognize and name the disease. He was also the first one to propose treating it by removing the appendix.18

The conservative British medical establishment resisted the novel appendectomy procedure until after the turn of the century, when it was used to save the new king's life. In 1901, the Prince of Wales, Albert Edward, underwent an emergency appendectomy, just two weeks before his scheduled coronation as King Edward VII. His successful recovery finally convinced British surgeons that this operation was the only way to save the victims of this "mysterious" new disease.20

Currently, 7% of the U.S. population will contract appendicitis at some point in their lifetime (according to www.emedicine.com). The figure would be even higher, except that 40,000 "incidental appendectomies" are performed each year (according to Harper's Index, Feb, 2002.) "Incidental" means there was nothing wrong with the appendix, but the surgeon happened to be operating on another organ nearby  in most cases performing a hysterectomy.

Appendicitis is the most common reason for a child to need emergency abdominal surgery. Young people between the ages of 11 and 20 are most often affected (according to www.KidsHealth.org).

Modern medicine recognizes that appendicitis is primarily a disease of the Western World.31 They attribute this to the (allegedly) greater amount of fiber in the diet of the Third World. However, the fiber theory has never been substantiated, as evidenced by this quote from www.KidsHealth.org:

There are no medically proven ways to prevent appendicitis. Although appendicitis is rare in countries where people eat a high-fiber diet, experts have not yet shown that a high-fiber diet definitely prevents appendicitis.

Many residents of the developing world, not wanting to appear "backward", feel obliged to adopt western toilets. This trend is causing health problems that were previously unknown among squatting populations. Appendicitis is one example, as reported by webhealthcentre.com, a health care portal based in India (retrieved in 2001):

The Indian type of toilet is more conducive to complete evacuation than the Western toilet. With the western style closets becoming popular in India, there is a risk of increased incidence of appendicitis.

Unfortunately, western doctors have never made the connection between toilet posture and appendicitis. Their understanding of this disease has advanced little in the century since Dr. Frederick Treves performed his famous appendectomy (mentioned above) on the Prince of Wales.

Ironically, Sir Frederick (knighted for saving the king's life) lost his own daughter to appendicitis.27 Despite being highly skilled at surgery, he had no idea what causes the disease, or how to prevent it.

Now his successors have a chance to redeem their profession. By informing their patients (and their children) about the health hazards of the modern toilet, they can prevent a great deal of needless suffering.

... a chronic and serious inflammatory disease of the gastrointestinal tract that affects more than 500,000 Americans. People with Crohn's disease may experience a number of symptoms including diarrhea, abdominal cramps and pain, fever, rectal bleeding, loss of appetite, and weight loss....The cause of Crohn's disease has not yet been discovered.

Inflammatory bowel disease (IBD) includes Crohn's Disease, ulcerative colitis and irritable bowel syndrome. IBD affects approximately 2 million Americans and can have devastating consequences. 20 to 40% of ulcerative colitis patients eventually require surgery for removal of the colon, according to the University of Maryland Medicine website. Up to 70% of patients with Crohn's disease require surgery at some point in their disease course to remove parts of the intestine.

IBD is confined to countries of the Western World, according to a study published in The Lancet.21 A 1997 article reported that "The last half of this century has seen a rising incidence of inflammatory bowel disease in developed countries," but notes "... the apparent absence of IBD in developing countries." [italics added]

For many years, researchers assumed that a different diet was protecting the developing world from IBD. "What else could it be?" They did not realize that these cultures have no uniform diet. For example, the Masai cattle-herders of central Africa are almost exclusively carnivorous. The Hindus of India are vegetarian. Other groups subsist on fish, or even on insects.

On testing their hypothesis, doctors were forced to conclude that "No special diet has been proven effective for preventing or treating this disease." (from the University of Chicago Hospitals website.)

Currently another theory has become popular among epidemiologists. They believe that fecal contamination of food and water in the developing world "naturally innoculates" children against inflammatory bowel disease. In other words, the Western World is too antiseptic to allow the immune system to produce the necessary antibodies.

This theory reflects a common misconception about the "superior hygiene" of the developed world. Westernized countries are proud of their high standards of cleanliness, but they are unaware that their internal cleanliness compares poorly with the rest of the world.

Colon hygiene depends on the effectiveness of daily elimination. Human beings were designed to perform their bodily functions in the squatting position. In order to be squeezed empty, the colon needs to be compressed by the thighs. Furthermore, the puborectalis muscle needs to be relaxed and the ileocecal valve from the small intestine needs to be closed. By ignoring these requirements, the sitting toilet makes it impossible to empty the colon completely.

Incomplete evacuation causes wastes to stagnate in the lower regions of the colon. In these areas, virulent bacteria can establish colonies, inflaming the surrounding tissues. Depending on where in the colon it occurs, and which strain of bacteria is involved, this inflammation is called by different names. Appendicitis, diverticulitis, ulcerative colitis, and Crohn's Disease can all be considered as various forms of inflammatory bowel disease. (Ileitis will be discussed below.)

Therefore, what protects the developing world is not "squalid conditions" but just the opposite: the natural cleanliness that comes from evacuating as nature intended. The relevance of toilet posture is also confirmed by the historical evidence. Inflammatory bowel disease and irritable bowel syndrome emerged in the West toward the end of the 19th century, as the use of sitting toilets became more and more common.22,28

An intestinal infection caused by strains of a common bacterium may be linked to the development of inflammatory bowel disease, a new study says. French researchers report that a heightened immune interaction between Escherichia coli and the cells lining the intestine may result in the symptoms experienced by people with inflammatory bowel disease (IBD). They suggest their work indicates antibiotics might be a useful tool when treating IBD.

Another form of Crohn's Disease is "ileitis" or inflammation of the small intestine. It results from fecal matter being forced backwards into the small intestine during evacuation. The ileocecal (IC) valve is designed to prevent this toxic "backflow"  but only in the squatting position. The IC valve needs to be supported by the right thigh in order to withstand the pressure built up during elimination. A more detailed explanation of this process can be found in two other sections: Contamination of the Small Intestine and Appendicitis.

The colon is a tube, five to six feet in length, which stores wastes from the small intestine and moves them, by rhythmic muscular contractions, to the rectum. In the process, water is continuously extracted, to prevent dehydration. If the flow is interrupted for any reason, the continual drying process can leave wastes "cemented" to the colon wall.

The sitting toilet obstructs the flow, because it ignores four basic requirements:

The sigmoid colon (the most common site for colon cancer) needs the support of the left thigh for complete evacuation. The thigh lifts the sigmoid and opens the kink where it joins the rectum.

The cecum (the second most common site for colon cancer) needs to be squeezed by the right thigh, which pushes wastes upwards into the ascending colon.

The rectum (the third most common site for colon cancer) needs to relax the grip of the puborectalis muscle, designed to prevent incontinence.

The entire colon needs to be compressed, with the ileocecal valve securely closed, to generate the required pressure for expulsion.

The kink where the sigmoid joins the rectum, mentioned above in point 1, serves an important function in preventing incontinence. It "applies the brakes" to the flow of peristalsis, reducing the pressure on the puborectalis muscle.

For safety, nature has deliberately created obstacles to evacuation that can only be removed by squatting. In any other position, the colon defaults to "continence mode." This is why the conventional sitting position deprives the colon of support from the thighs and leaves the rectum choked by the puborectalis muscle.

These obstacles make elimination difficult and incomplete  like trying to drive a car without releasing the parking brake. Chronically incomplete evacuation, combined with the constant extraction of water, causes wastes to adhere to the colon wall. The passageway becomes increasingly constricted and the cells start to suffocate. Prolonged exposure to toxins will often trigger malignant mutations.

This explanation would suggest that colon cancer is related to constipation. According to a 1998 report in the journal, Epidemiology,3 "People who frequently felt constipated were more than four times as likely to develop colon cancer as those who did not complain of constipation." The study also found that using commercial laxatives frequently was associated with "substantially increased risk of colon cancer."

A Lesson from the Developing World

In contrast with constipated western societies, the developing world is relatively free of colon cancer, as this 2009 study found:

Colorectal cancer, however, is not uniformly common throughout the world. There is a large geographic difference in the global distribution of colorectal cancer. Colorectal cancer is mainly a disease of developed countries with a Western culture. In fact, the developed world accounts for over 63% of all cases. The incidence rate varies up to 10-fold between countries with the highest rates and those with the lowest rates.

For decades, researchers have been trying to explain the absence of colon cancer in the developing world. Some have speculated that perhaps E. coli bacteria in the water and food somehow stunts the growth of cancer cells in the intestine.

This theory reflects the common belief that our society is "clean" while the developing world is "dirty." In terms of colon hygiene, exactly the opposite is the case. What protects the developing world from bowel disease is the natural cleanliness that comes from evacuating as nature intended. By contrast, our contrived toilet posture leads to fecal stagnation  the primary cause of colon cancer and inflammatory bowel disease.

Dr. Burkitt's Mistake

Lacking this knowledge, researchers have focused on dietary factors. They have repeatedly tried to prove that a high-fiber diet prevents colon cancer. This theory dates from the early 1970's when Dr. Denis Burkitt (1911-1993), a British missionary doctor (pictured here), reported a dramatic difference between colon cancer rates in America and Africa. According to his article in the Journal of the Royal Society of Medicine, colon cancer is nearly 15 times as common in black Americans as in Africans.40

Dr. Burkitt believed that high levels of fiber in the African diet protected the natives from bowel disease. However, at least three recent major studies have shown the fiber theory to be incorrect, as reported by the Associated Press:

Study: Fiber Doesn't Prevent Cancer

By Emma Ross -- AP Medical Writer

October 13, 2000

LONDON (AP) - Evidence is mounting that fiber might not prevent colon cancer after all, with a new study suggesting that one type of supplement might even be bad for the colon.

The theory that a high-fiber diet wards off the second-leading cancer killer has been around since the 1970s, but the evidence was never strong. The concept began to crumble last year when the first of three major U.S. studies found it had no effect.

In the latest study, published this week in The Lancet medical journal, European researchers found that precancerous growths, or polyps, were slightly more likely to recur in those taking a certain fiber supplement.

The above article appeared on October 13, 2000. Five years later, medical researchers  at their wits' end  were still testing the same discredited theory. On December 14, 2005, The Boston Globe reported on the latest attempt by the Harvard School of Public Health:

Eating a lot of fiber-rich vegetables, fruits, and whole grains does not appear to reduce a person's chances of getting colorectal cancer, researchers found in the largest study yet to test the popular and longstanding idea about preventing the third most common cancer....

"It became an urban myth," said Dr. David Ryan, medical director of the gastrointestinal cancer center at Massachusetts General Hospital. ''It takes a lot of time to deconstruct those."....

Dr. Denis Burkitt obviously guessed wrong  and led the western world on a "wild goose chase" for over three decades. But, in his defense, it should be noted that he was aware of the health benefits of squatting. His 1979 best-selling book Don't Forget Fibre in Your Diet (translated into 9 languages) acknowledges that the Africans' use of squat toilets might be as important as their diet in protecting them from colon cancer and other diseases.

Western researchers ignored this hypothesis, partly because toilet posture was considered a taboo subject. They also probably believed that the western world could never revert to squatting, even if sitting toilets were proven to be harmful. So, they simply hoped that modifying the diet would be enough.

Now that the fiber theory has clearly failed, they will have to reconsider Dr. Burkitt's alternate explanation. They may be surprised by the public's openness to a simple change that could save many lives.

Constipation, especially when chronic, can have very damaging effects on the colon. The colon is constantly extracting water from its contents, to transform liquid wastes into solid. As a result, if elimination is not regular and complete, the wastes will dry and become cemented to the walls of the colon.

Constipation has been shown to increase the risk of colon cancer3 and has been implicated in diverticulosis and appendicitis. "Cumulative lifetime use of commercial laxatives was also associated with increased risk of colon cancer."3

Gravity does most of the work. The weight of the torso presses against the thighs and naturally compresses the colon. Gentle pressure from the diaphragm supplements the force of gravity.

The ileocecal valve, between the colon and the small intestine, is properly sealed, allowing the colon to be fully pressurized. The pressure creates a natural laxative effect. In the sitting position the IC valve is unsupported and tends to leak, making it difficult to generate the required pressure.

Squatting relaxes the puborectalis muscle which normally chokes the rectum to maintain continence.

Squatting lifts the sigmoid colon to unlock the "kink" at the entrance to the rectum. This kink also helps prevent incontinence, by taking some of the pressure off the puborectalis muscle.

To summarize, the colon is equipped with an inlet valve (the ileocecal valve) and an outlet valve (the puborectalis muscle). Squatting simultaneously closes the inlet valve, to keep the small intestine clean, and opens the outlet valve, to allow wastes to pass freely. The sitting position defeats the purpose of both valves, making elimination difficult and incomplete, and soiling the small intestine.

The sphincter muscle, commonly regarded as the outlet valve, is actually not capable of preventing incontinence. It involves voluntary effort and is only for short-term emergencies. Maintaining continence requires the continuous grip of the puborectalis muscle. This grip is not released in the sitting position, so it must be forced open by straining. Straining repeatedly over a number of years can lead to hemorrhoids, which can therefore be classified as a repetitive strain injury.

Doctors have long recognized the connection between sitting toilets and constipation. For example, F.A. Hornibrook in The Culture of the Abdomen, published in 1933:

Man's natural attitude during [elimination] is a squatting one, such as may be observed amongst field workers or natives. Fashion, in the guise of the ordinary water closet, forbids the emptying of the lower bowel in the way Nature intended. Now in this act of [elimination] great strains are imposed on all the internal organs .

It is no overstatement to say that the adoption of the squatting attitude would in itself help in no small measure to remedy the greatest physical vice of the white race, the constipation that has become a contentment.5

u

These sentiments are echoed in Our Common Ailment, written by H. Aaron and published in 1938:

When the thighs are pressed against the abdominal muscles in this position, the pressure within the abdomen is greatly increased, so that the rectum is more completely emptied. Our toilets are not constructed according to physiological requirements. Toilet designers can do a good deal for people if they will study a little physiology and construct seats intended for proper [elimination].6

In April, 2002, an Iranian radiologist, Dr. Saeed Rad, published a study which compared the effectiveness of sitting versus squatting for evacuation.24 One of his conclusions relates to the cause of a type of hernia known as "rectocele," which is a bulge of the front wall of the rectum into the vagina.

Thirty subjects participated in the study  21 male, 9 female  ranging in age from 11 to 75 years. Each patient received a barium enema so the internal mechanics of evacuation could be recorded on an X-Ray image. Each patient was studied in both the squatting and the sitting positions.

Using these images, Dr. Rad measured the angle where the end of the rectum joins the anal canal. At this junction point, the puborectalis muscle creates a kink to prevent incontinence. Dr. Rad found that when the subjects used sitting toilets the average angle of this bend was 92 degrees, forcing the subjects to strain. When they used squat toilets, the angle opened to an average of 132 degrees. At times it reached 180 degrees, making the pathway perfectly straight.

Using squat toilets, all the subjects reported "complete" evacuation. "Puborectalis relaxation occurred easily and straightening of the rectum and anal canal facilitated evacuation. The anal canal became wide open and no folding was noticed in the terminal rectum."

In the sitting position, "a remarkable folding was created in the terminal rectum predisposing it to rectocele formation, and puborectalis relaxation was incomplete." All the subjects reported that elimination felt "incomplete" in the sitting position.

Dr. Rad also measured the distance from the pelvic floor to the perineum. In the sitting position he found that the pelvic floor was pushed downwards to a significant degree. (A detailed discussion of the connection between sitting toilets and pelvic organ prolapse  including rectoceles  can be found in the gynecological disorders section.)

Dr. Rad concluded that the use of the squat toilet "is a more comfortable and efficient method of bowel evacuation" than the sitting toilet.

Dr. William Welles, a San Diego chiropractor, discovered that the modern toilet causes fecal contamination of the digestive system in 70 to 80% of the population.

The ileocecal (IC) valve, between the small intestine and the colon, is designed to prevent the backflow of wastes. If it leaks, E.coli bacteria can enter the small intestine and get absorbed into the bloodstream. This puts a strain on the liver which has to remove these toxins.

The invasion of fecal bacteria (called "colo-ileal reflux") can also cause inflammation of the small intestine. This condition is called "ileitis" and is a form of Inflammatory Bowel Disease.

According to Dr. Welles,

My discovery of a dysfunctional ileocecal valve in approximately 80% of my patients is also confirmed by modern medicine. The ICV is so commonly found to be dysfunctional in surgeries of the bowel and in barium enema studies that it is believed to be inherently faulty in its design.2

Drawing on the research of F.A. Hornibrook, Dr. Welles suspected that the faulty design responsible for this problem was not nature's but man's.

Hornibrook states that the design of the Western toilet defies the laws of nature by encouraging the user to bear down without the natural support given the abdominal walls by the thighs when one is in the squatting posture.2

Then, he used muscle-testing to verify his hypothesis.

When individuals sat in the position encouraged by the western toilet and bore down so as to eliminate fecal matter, the muscles weakened immediately and the ileocecal valve was blown out....The ICV is critical to proper intestinal plumbing, and its dysfunction is the root cause of many of the diseases of modern civilization....
2

In his article, Dr. Welles also discusses other ailments caused by the sitting toilet  including colon cancer, hemorrhoids, hernias and pelvic organ prolapse. He concludes with some strong words of advice:

Cast aside your preconceived ideas as to what is normal and use your rational mind to act on what has been stated above. At any given time in history it is possible to look back and find great faults with the habits of previous civilizations. I believe that future generations will one day look back at our aberrant habit of using the modern toilet  and cringe.

Diverticulosis is a type of hernia caused by years of chronic straining. The outer layer of the colon ruptures, allowing the inner lining (the "mucosa") to bulge out in pouches or sacs. It is similar to an inner tube that bulges out through weak spots in a worn-out tire.

Diverticulosis typically occurs in the sigmoid colon, in the lower left section of the abdomen. According to the National Digestive Diseases Information
Clearinghouse:

About half of all Americans age 60 to 80, and almost everyone over age 80, have diverticulosis.
When the pouches become infected or inflamed, the condition is called diverticulitis. This happens in 10 to 25% of people with diverticulosis...

... Diverticulitis can lead to complications such as infections, perforations or tears, blockages, or bleeding. These complications always require treatment [surgery] to prevent them from progressing and causing serious illness.1

These statistics might seem to imply that diverticulosis is an inevitable part of growing old. Dr. Berko Sikirov, the Israeli physician who conducted successful clinical research on the use of squatting to treat hemorrhoids, disagrees:

Colonic diverticulosis develops as a result of excessive straining at defecation due to habitual bowel emptying in a sitting posture, which is typical of Western man. The magnitude of straining during habitual bowel emptying in a sitting posture is at least three-fold more than in a squatting posture and upon urge. The latter defecation posture is typical of latrine pit users in underdeveloped nations.

The bowels of Western man are subjected to lifelong excessive pressures which result in protrusions of mucosa through the bowel wall at points of least resistance. This hypothesis is consistent with recent findings of elastosis of the bowel wall muscles, the distribution of diverticula along the colon, as well as with epidemiological data on the emergence of diverticulosis coli as a medical problem and its geographic prevalence.9

The geographic prevalence mentioned by Dr. Sikirov is confirmed by medicinenet.com, a well-respected medical website:

Diverticular disease is common in the Western world but is extremely rare in areas such as Asia and Africa.

Mainstream medicine has never considered the relevance of evacuation posture to diverticulosis. They attribute its high prevalence in our society to "insufficient dietary fiber." But they offer no evidence to support their theory. (The same theory was used for decades to explain colon cancer until it was disproved by several recent studies.)

An excerpt from The Mayo Clinic on Digestive Health illustrates a common fallacy used to promote the theory:

Diverticular disease emerged after the introduction of steel rolling mills, which greatly reduced the fiber content of flour and other grains. The disease was first observed in the United States in the early 1900's around the time processed foods became a mainstay of the American diet ...23

The Mayo Clinic is correct to blame a technological innovation  but which one? The same Industrial Revolution that produced the steel rolling mill also made the porcelain throne a fixture throughout the western world.22

Dr. Denis Burkitt, the British surgeon who popularized the fiber theory, also strongly advocated the use of squat toilets to prevent diverticulosis and hiatus hernias.41 His only mistake was to assume that diet was the crucial factor and squatting was secondary, instead of the other way around.

The claim that dietary fiber protects against diverticulosis was finally tested in a recent study involving 2,104 participants, 3080 years old. They underwent outpatient colonoscopies from 1998 to 2010 and were interviewed regarding diet and physical activity.

The study, published in the February, 2012 issue of Gastroenterology, found that "A high-fiber diet and increased frequency of bowel movements are associated with greater, rather than lower, prevalence of diverticulosis. Hypotheses regarding risk factors for asymptomatic diverticulosis should be reconsidered."

In a media interview, the lead author, Anne F. Peery, MD put it more bluntly: "Our study makes it clear that we don't really understand why diverticula form."

The journal article also discusses the impact of this disease on health care costs:"The complications of diverticulosis cause considerable morbidity in the United States; health care expenditures for this disorder are estimated to be $2.5 billion per year."

To solve their "mystery," the researchers need to examine the biomechanics of evacuation. They will find that a western toilet strains the sigmoid colon in three ways:

Since the exit is obstructed, wastes get backed up in the sigmoid colon, where they stagnate, putting constant pressure on the colon wall.

The colon is deprived of the natural support provided by the thighs when squatting. As mentioned above, diverticulosis is a type of hernia. In the squatting position, the thighs serve the same function as the belt worn by a weightlifter to prevent hernias.
(Note: Those who have grown up deprived of squatting may have lost the flexibility in their hips. Such individuals may not be able to press their thighs against their abdomen and may not be fully protected against hernias and diverticulosis.)

95% of diverticular disease occurs in the sigmoid colon. This is due to the sharp bend or "kink" where the sigmoid joins the rectum (shown here.) Dr. William Welles explains:

As we bear down without proper support, it increases the degree of kinking at this junction, and limits the amount of elimination to whatever is below the kink. 2

Straining is therefore counterproductive  but unavoidable  as long as we persist in using an unnatural toilet posture. The self-inflicted injury called "diverticulosis" is the inevitable result.

Dr. Berko Sikirov is an Israeli physician who has spent over 20 years studying the effects of excessive straining caused by the use of sitting toilets. His research on hemorrhoids and diverticulosis is discussed elsewhere on this webpage.

In 1990 he published an article entitled "Cardio-vascular events at defecation: are they unavoidable?" He begins by describing the problem:

Probably every physician practicing emergency medicine has encountered tragic cases of sudden death in the lavatory. Patients with acute coronary events are especially vulnerable to excessive straining which accompanies defecation. Therefore, it is a routine practice in coronary care units to administer laxatives or stool softeners, hopefully to reduce straining ...10

The article goes on to explain how straining on the toilet can be avoided by adopting the natural squatting position. In the following summary, Dr. Sikirov uses the term "Valsalva Maneuver," which means pushing down with the diaphragm while holding one's breath.

According to the American Heritage Dictionary, this maneuver "increases pressure within the thoracic cavity and thereby impedes venous return of blood to the heart." Another term used below is "syncope" which means "fainting."

Cardio-vascular events at defecation are to a considerable degree the consequence of an unnatural (for a human being) seated defecation posture on a common toilet bowl or bed pan. Excessive straining, expressed in intensively repeated Valsalva Maneuvers, is needed for emptying the bowels in the sitting position. The Valsalva Maneuver adversely affecting the cardio-vascular system is the causative factor of defecation syncope and death.

The cardio-vascular system of a healthy man withstands the intensive and repeated straining at defecation, while the compromised cardio-vascular system may fail, resulting in syncope or even death. The squatting defecation posture is associated with reduced amounts of straining and may prevent many of these tragic cases.10

Surveys suggest that, in westernized countries, as much as half the population over 40 years of age may suffer from hemorrhoids.8

The common explanation for their absence in the developing world is "a high fiber diet." An Internet search on "incidence of hemorrhoids" turns up many instances of the following statement, carefully worded to suggest a causal connection: "Populations in which fiber intake is high have a very low incidence of hemorrhoids."

The medical establishment accepted the fiber theory without proof because they had no other explanation for the dramatically lower incidence of hemorrhoids in the developing world. They ignored the fact that these populations follow a wide variety of diets. The Masai cattle-herders of central Africa are almost exclusively carnivorous. The Hindus of India are vegetarian. Other groups subsist on fish, or even on insects.

Researchers have also been unaware of another, more relevant factor which would explain the data: the use of squat toilets. This factor has three advantages over the fiber theory:

It is consistent throughout the developing world.

It pertains directly to the anatomy of hemorrhoids.

It has been validated by published clinical research.

The research was conducted by Dr. Berko Sikirov, an Israeli physician, who studied the effect on hemorrhoid patients of squatting for elimination. The results were published in 1987 in the Israel Journal of Medical Sciences.7 In 1996, the study was the subject of an article in the Townsend Letter for Doctors and Patients.8

Twenty male and female patients who had hemorrhoids of varying degrees of severity participated in the study. They had all used conventional treatments with little or no success. Two of the patients had been treated with ligation (tying off the hemorrhoid at its base with a rubber band.)

The patients underwent a proctoscopy at the beginning of the trial. Then they were told to change their toilet habits in two ways: to wait until the urge to evacuate was strong (to avoid straining) and to use the natural squatting position for elimination. The proctoscopy was repeated after one year.

Of the 20 patients, 18 reported within a few days to a few months a significant reduction or complete absence of symptoms. Lack of improvement in the two other patients, who had previously had ligation for hemorrhoids, "may be ascribed to fibrous tissue development in the submucosa as a consequence of the ligation."7

Follow-up examinations, 12 and 30 months later, on the 18 other patients (90% of the subjects in the study), revealed no recurrence of the symptoms. This chart shows the results obtained by all 20 patients. A detailed account of Dr. Sikirov's research can be found in his U.S. Patent #4,819,277.

Dr. Sikirov's conclusion is that hemorrhoids result from continual aggravation and injury due to excessive straining in the sitting position. Straining is necessary to overcome the constriction in the rectum designed to maintain continence. When this ongoing insult to the body is removed by returning to the squatting position, the natural healing process can occur without hindrance.

The importance of squatting is not unknown to gastroenterologists and proctologists. Dr. Michael I. Freilich, a retired colorectal surgeon from Marina del Rey, California, recently commented,

Back in 1979, when former President Carter had a hemorrhoid problem, Time Magazine called and asked me to explain the cause of hemorrhoids. In the magazine, I was quoted as saying,"Man was not meant to sit on a toilet, but to squat in a field."

Even the standard textbook, Bockus Gastroenterology, contains the statement, "The ideal posture for [evacuation] is the squatting position, with the thighs flexed upon the abdomen. In this way the capacity of the abdominal cavity is greatly diminished and intra-abdominal pressure is increased, thus encouraging expulsion ..."11

Unfortunately, most proctologists pretend to be unaware of the therapeutic value of squatting. Surgery and ligation are lucrative procedures. Not wanting their income to suffer, they cause their patients to suffer instead.

A hiatus hernia (also called "hiatal hernia") occurs when the upper part of the stomach bulges into the chest cavity through a tear or weakness in the diaphragm. It is often associated with GERD (gastroesophageal reflux disease) in which stomach acid leaks into the esophagus. GERD causes chronic heartburn and increases the risk of esophageal cancer.

In 1981, Dr. Denis Burkitt, writing in the American Journal of Clinical Nutrition, proposed a link between western toilets and hiatus hernias. His paper cites the much higher pressure on the diaphragm while sitting (versus squatting) for evacuation. He also cites strong epidemiological evidence:

Hiatus hernia has its maximum prevalence in economically developed communities in North America and Western Europe. Very large series of upper gastrointestinal tract radiological examinations indicate that this defect can be demonstrated in over 20% of North American adults [of all races].

In contrast, the disease is rare in situations typified by rural African communities. In a careful prospective radiological study of the upper gastrointestinal tract in Nigerians, hiatus hernia was detected in only four of 1030. In Kenya, only one case was found in over 1000 barium meal examinations and in Tanzania, one in over
700 barium studies.41

In 1999, gastroenterologist Dr. Stephen Sontag expanded still further the indictment of the western toilet. The following excerpt summarizes his paper, "Defining GERD," published in the Yale Journal of Biology and Medicine: 42

The antireflux barrier in children and adults is gradually weakened over time as a result of chronic straining to defecate and straining in an unphysiologic position, both of which stem from our modern day habits of eating a low-fiber diet and living on the high-seated toilet. We suggest that the chronic traumatic hiatal hernia is

the cause of more than 90 percent of the GERD that stalks the Western world;

a direct result of abandoning the popular and worldwide practice of squatting to socialize, eat and defecate; and

our just reward for adopting the "civilized" high sitting position on chairs and modern toilets.

Dr. Sontag's detailed explanation, contained in his twelve-page article, can be found at the journal's website.

To summarize, the diaphragm was not designed to be the "workhorse" for evacuation. Like all primates, humans were designed to squat for bodily functions. Squatting pushes the colon against the thighs by the force of gravity and effortlessly creates the required pressure for expulsion. The daily abuse of the diaphragm caused by the western toilet is the reason for the high incidence of hiatus hernias and GERD in our society.

Mr. Wallace Bowles is an Australian researcher who learned about the benefits of squatting in 1984, at the age of 52. A former Royal Australian Air Force fighter pilot and later a senior commercial pilot, Mr. Bowles in 1984 was working for the Australian Aviation Authority as an investigator of aircraft accidents.

Although he had no formal medical training, his intense curiosity led him to immerse himself in the study of human anatomy, in order to understand why squatting for bodily functions was so much more effective. He also suspected that the habitual use of sitting toilets might be responsible for some common ailments found only in westernized countries.

As a man in his fifties, Mr. Bowles was naturally curious about a possible connection to prostate problems. He was intrigued by evidence such as the following:

from USA Today, January 5, 2000:

African Americans have the highest prostate cancer risk in the world .... And despite high rates among African Americans, prostate cancer is very low in Africa.

A 200-fold difference in incidence exists between African American men, who represent the group with the highest incidence of the disease, and Chinese men living in Asia, in whom the incidence of prostate cancer is among the lowest in the world.

Migration studies reveal that movement of people from areas of low risk to areas of high risk is associated with an increase in the incidence of prostate cancer among the migrants. In one study, within one generation, the increase in incidence in Japanese immigrants was 4- to 9-fold compared to the incidence of prostate cancer in Japan.

In his review of the medical literature, Mr. Bowles encountered the usual explanation for the low incidence of prostate cancer in the developing world: a diet low in fat and high in fiber. He was skeptical of this theory, and a recent major study has confirmed his doubts:

(American Society of Clinical Oncology - August 30, 2002)  A low-fat, high-fiber diet heavy in fruits and vegetables has no impact on PSA levels in men over a four-year period, and does not affect the incidence of prostate cancer, according to a study by researchers at Memorial Sloan-Kettering Cancer Center, the National Cancer Institute, and seven other centers.
[http://www.prostatecancer.on.ca/WNew/nov2002_03.html]

Mr. Bowles took an entirely different approach to the problem. He suspected that the prostate's strange behavior was caused by a breakdown in the body's system of communication and control. The prostate and bladder are controlled by the pudendal nerve, which emerges from the sacrum, near the base of the spine, and runs along the perineum. Damage to this nerve can weaken the brain signals to and from the prostate and render the gland dysfunctional.

In women, the pudendal nerve is commonly injured during childbirth, leading to temporary or permanent bladder incontinence. Pelvic nerve injury often results from instrumental deliveries (forceps, vacuum extractors, etc.) and from straining to overcome the unnatural western delivery posture. (More details in the Pregnancy and Childbirth section.)

But childbirth is not the only way the pudendal nerve is damaged. It happens to women who have never had children, as well as to men. Mr. Bowles theorized that the same stretching of the pelvic floor caused by giving birth in the recumbent position could also result from evacuating in the sitting position. Bowel evacuation is not as stressful as childbirth, but is repeated on a daily basis.

The pelvic floor is a hammock of muscles which supports the bladder, the intestines and (in women) the uterus. The pudendal nerve travels from the spinal cord through the pelvic floor to the bladder and prostate. On a conventional toilet, the pelvic floor is unsupported and is forcefully pushed downwards during evacuation.

The practice of holding one's breath and pushing with the diaphragm is considered "normal" in western societies. But no other animal uses this "Valsalva Maneuver." Like all primates, man was designed to use the squatting position, which empties the colon without putting any pressure on the pelvic floor.

Instead of pushing downwards with the diaphragm, squatting pushes upwards with the thighs. The weight of the torso compresses the colon, so no straining is required. Squatting also relaxes the puborectalis muscle to straighten the rectum. This is the method used by over two-thirds of humanity.

How does seated evacuation damage the pudendal nerve? The nerve passes through the pelvic floor and has to stretch each time the Valsalva Maneuver is used. Nerves are not elastic and cannot be stretched very far without being damaged. A 12% stretch destroys a nerve. 16

Over the years, the pelvic hammock sags lower and lower, from being pushed downwards several times each day. The pudendal nerve is eventually stretched beyond its capacity. It loses the ability to transmit brain signals and supply electrical energy to the pelvic area.

Every gland in the body requires constant feedback from the brain to maintain normal functioning. Damage to the pudendal nerve disconnects the prostate from the body's governing intelligence. The prostate "loses its mind"  as millions of men discover each year, to their dismay.

Prostate disease affects 75% of the male population over the age of 50.39 It can take three different forms:

Enlargement. Unaware that it is strangling the urethra, the prostate can grow from its normal size of a walnut, to the size of an orange, or even larger. More than half the men in the United States between the ages of 60 and 70 and as many as 90% between the ages of 70 and 90 have symptoms of BPH [prostate enlargement] according to the National Cancer Institute.

Cancer. The overactive cells will frequently mutate and become malignant. Each day in the United States, more than 100 men die of prostate cancer. Annually, physicians diagnose 184,500 new cases, and treatment costs approach $5 billion (according to emedicine.com.)

Prostatitis. "Symptoms of prostatitis-like pain occur in 11% of American men, and approximately 95% of the men whose conditions are diagnosed as chronic prostatitis have no evidence of bacterial infection or inflammatory cells in the prostatic fluid....Chronic perineal pain may be caused by pudendal nerve entrapment (PNE)." 29

The term "entrapment" refers to nerve damage of various kinds, including stretching of the pudendal nerve. The above explanation may also apply to cystitis  another pelvic disorder which, in many cases, seems to have no discernible cause.

Damage to the pudendal nerve occurs gradually and cumulatively and can take many years to manifest. This is one reason why the cause has escaped detection. Another reason is cultural insularity. Sitting toilets were considered normal and natural and so, above suspicion.

To test his theory, Mr. Bowles designed and manufactured a squatting device, and encouraged thousands of his fellow Australians to adopt the natural posture for evacuation. Here is his summary of the results:

An ongoing informal study indicates that, providing prostate enlargement has not progressed too far, symptoms gradually reverse when men abandon seated bowel movements and squat instead. The study indicates that improvement usually occurs within three months and, within about six months of making this posture change, most men (including men in their seventies) regain normal prostate function. 14

Mr. Bowles concluded that the damaged nerves will grow back over time if the source of injury is removed. Many respondents also reported significant reductions in their PSA levels (prostate specific antigen) after switching to squatting.

Wallace Bowles did not invent the concept of "pelvic floor nerve stretch injury." He simply realized that this self-inflicted injury has been institutionalized by the universal habit of sitting for evacuation. He therefore concluded that the porcelain throne is the most likely culprit in the mysterious epidemic of pelvic disorders (male and female) that plagues the Western World.

This "eureka!" of a retired aircraft accident investigator may someday be recognized as one of the most important breakthroughs in the history of medicine.

In the larger cities of Asia, many residents have abandoned their traditional customs, believing that the West is more progressive and somehow "superior." By adopting western toilets, they have unwittingly introduced new diseases into their society. A recent article in the Malaysian newspaper The Star (March 30, 2003) discusses one such ailment:

To squat or not to squat? That is the question. Actually, your toileting technique may have an effect on urinary incontinence. There is a lot of evidence to show that the Asian technique of using the toilet goes a long way to maintaining better pelvic health than the Western technique, says professor Ajay Rane, James Cook University of Medicine (Australia) consultant urogynecologist and pelvic reconstructive surgeon.

According to Rane, a study done in Hong Kong showed that city-dwelling women had more urinary incontinence and bowel problems than country dwelling women. "The basic differences in these women were not their body weight, or how many children they had, but their toileting habits," he says.

In general, women in urban areas use the "sit" method while the rural women use "squat" toilets. "Basically, we believe that the study suggests squatting causes the angle of the pelvis to relax much better and give better pressure. When you are sitting, you do not have the right relaxation of the muscles and the angle of the pelvis," he says. "I strongly believe that the squatting technique has tremendous beneficial effects on the pelvis."

Dr. Rane's view is shared by Dr. Stuart Stanton, Chairman of the Continence Foundation and Consultant Urogynecologist at St. George's Hospital, London:

"Squat" toilets are an excellent way for women to exercise their perineum and pelvic floor muscles and control their urinary stream from the age of 2½-3 years onwards. Reports from the developing world suggest that urinary incontinence is much less in women who squat.

Here is a brief explanation of why sitting toilets increase the risk of incontinence: The pelvic floor is a hammock of muscles that supports the intestines, the bladder and the uterus. Western toilets force the user to strain when evacuating, repeatedly subjecting the pelvic floor to unnatural stress. The downward pressure stretches and weakens the pudendal nerve, responsible for bladder control.

To maintain continence, the brain needs to constantly monitor the pressure within the bladder and issue commands to the urethral sphincter muscle. Both functions are impaired when the pudendal nerve is weakened by the descent of the pelvic floor. The following statistics from FocusOnUrology.com show how frequently this occurs:

50% or more of elderly persons living at home or in long-term care facilities are incontinent.

FocusOnUrology.com attributes incontinence mainly to childbirth, weakened pelvic muscles, hormonal changes associated with menopause, and (in men) prostate surgery. Due to their cultural conditioning, they do not mention the use of the reclining posture for childbirth. The modern toilet has made women incapable of prolonged squatting, the position designed by nature to protect the pelvic floor during delivery.

Nor do they mention the direct effect of using a sitting toilet, which causes the pelvic floor to be pushed downwards each time one strains to evacuate. Based on a conservative estimate that the average person strains four times for each daily evacuation, by the age of 50 the unsupported pelvic floor has been stretched 73,000 times.

An unnatural maneuver repeated so many times inevitably causes a "repetitive stress injury." The pudendal nerve is the main casualty of this unintentional abuse, which renders incontinent over 50% of elderly Americans (statistics above.)

Other westernized countries face a similar problem. Researchers at Adelaide University in Australia recently reported that incontinence and other pelvic floor disorders are much more prevalent than previously believed. The article is entitled "The Descent of Women  a Silent Epidemic" (23 November 2000):

Adelaide University researchers, in the first comprehensive study of its kind in the world, have found a remarkably high prevalence of pelvic floor disorders in the general population.... Most of these complaints were still common among women who had never had a vaginal birth.... "The survey highlights the high prevalence and major social impact of pelvic floor prolapse and incontinence in our society," said Professor MacLennan. "It is a silent epidemic, as those with the problem are often embarrassed to talk about it," he said.

sciencedaily.com/releases/2000/11/001122231619.htm

Until recently, the cause of this epidemic has been a mystery (Professor MacLennan, quoted above, believes that it is unavoidable, as long as women continue to give birth.) But research by Mr. Wallace Bowles on the relevance of the squatting posture has brought a new understanding of how to prevent (and, in many cases, correct) these disorders:

Most people with urinary incontinence experience a noticeable improvement within several weeks of commencing to squat for defecation with complete correction within about 3 months.17

Anecdotally, a number of women who squat, habitually, for bowel movements and who have experienced pelvic floor trauma and incontinence after the birth of their baby, have regained their continence within about six weeks when they continue to adopt the squat posture for bowel evacuation.13

Even children are susceptible to pelvic floor nerve stretch injury. An article entitled "My Child, My Teacher" was published in the Spring, 1998, issue of New Vegetarian and Natural Health Magazine.15 Focusing on the benefits of squatting for children, the article contains numerous reports of bedwetting corrected by this simple change of habit.

Childbirth educators always advise pregnant women to avoid the "Valsalva Maneuver," which means holding one's breath while straining. It puts great pressure on the uterus and the pelvic floor.

Unfortunately, this maneuver is impossible to avoid when using a conventional toilet. This is why expectant mothers find daily elimination such an uncomfortable and frustrating experience. Constipation during pregnancy is considered "normal" because most doctors are unaware of the abnormal design of the modern toilet.

Besides improving elimination, squatting also helps in other ways during pregnancy:

Preventing hemorrhoids, which affect up to 50% of pregnant women (according to aHealthyMe.com)

Avoiding the build-up of toxins in the colon, to give the growing embryo a cleaner, healthier environment.

Developing the flexibility needed for giving birth in the most advantageous and natural posture. Squatting fully opens the birth canal, maximizes the power of the abdominal muscles, and helps protect the pelvic floor from injury.

This Yoga posture is called "malasana preparation."It cultures flexibility for natural childbirth (and elimination.)It's easier with your back against the wall.

A study published in 1969 in the Journal of Obstetrics and Gynaecology of the British Commonwealth found that squatting increases the available area in the birth canal by 20 to 30%.25 The sitting toilet has made women incapable of prolonged squatting, which would promote a quicker and more comfortable labor and delivery. It would also reduce the need for medical interventions such as forceps, vacuum extractors, epidurals and episiotomies.

The most drastic form of medical intervention is the cesarean section. 32% of US births in 2007 were by C-section.37 This alarming statistic indicates that women are losing the ability to give birth naturally. The modern toilet has alienated women from the birthing posture they were designed to use.

The conventional delivery positions  recumbent and semi-sitting  close the birth canal by 20 to 30%.25 The baby is used as a "wedge" to force the birth canal open. Obstetricians, unaware of what is causing the obstruction, resort to drugs and elaborate appliances to "extract" the fetus. Their crude and forceful procedures increase the risk of injury to mother and baby.

Almost all hospital delivery rooms prohibit the use of the squatting position, so women are forced to use the Valsalva Maneuver. They hold their breath and push with all their might  oblivious to the fact that the birth canal is partially closed. This maneuver puts enormous strain on the pelvic floor.

A common result is damage to the pudendal nerve, which connects the pelvis to the spinal cord. Nerve damage can lead to bladder incontinence and hormonal imbalance, due to the breakdown in communication between the brain and the pelvis. Post-partum depression is one symptom of hormonal imbalance.

Giving birth in the squatting position does not require the Valsalva Maneuver. Besides fully opening the birth canal, the posture naturally compresses the abdominal cavity to push the baby along, without great exertion or holding of breath.

The full squatting posture also minimizes the risk of pelvic hernias, often caused by straining during delivery. The bladder, the uterus, or the intestines can be dislodged from their proper place and pushed into the vagina. These hernias are extremely common in the western world. But in the developing world, where squatting is used, women are "relatively unaffected by pelvic floor problems."36

Human beings should be able to give birth as easily as any other animal. This is the case for over two-thirds of the world's women, since they use the same posture they have used all their lives for bodily functions.

By rediscovering how the body was designed to function, women can greatly reduce the stress of pregnancy and childbirth. Having a baby will never be effortless, but it can become a much safer, easier and more joyful experience.

Each year more than 600,000 hysterectomies are performed in the United States. About one-third of American women undergo this operation by the age of 60.

It is performed to deal with a number of different diseases, including uterine fibroids, endometriosis, uterine prolapse and cancer. More information about hysterectomies can be found at the National Womens Health Information Center website.

The website states that "no one knows the cause" of these diseases. But the fact that one out of every three women has her uterus removed indicates that something in our culture is fundamentally wrong.

Before the 19th century, hysterectomies were so rare that "most doctors were of the opinion that it was unlikely that one could survive a hysterectomy." 32 The sharp increase in uterine disorders toward the end of the 19th century coincided with a similar rise in prostate disorders,33 leading to the suspicion that the two trends were somehow connected.

The connection became clearer as doctors learned more about another common pelvic ailment: bladder incontinence. They found that it typically results from damage to the pudendal nerve, which connects the pelvis to the spinal cord. This damage was traced to a "stretch injury"  caused by the progressive descent of the pelvic floor.

Why the Pelvic Floor Descends

The Australian researcher, Mr. Wallace Bowles, has offered the most plausible explanation for the high incidence of pelvic floor prolapse in the western world. (Other scientists, including Dr. William Welles, a San Diego chiropractor, independently proposed the same theory.)2 They observed that the sudden emergence of pelvic diseases near the end of the 19th century coincided with the adoption of sitting toilets.22

Furthermore, they recognized that the porcelain throne is an "ergonomic nightmare" because it forces one to use the Valsalva Maneuver (holding one's breath and pushing down with the diaphragm.) No other animal uses this maneuver. The pelvic floor was not designed to handle this type of stress on a daily basis.

Like all primates, man was designed to use the squatting position, which empties the colon without putting any pressure on the pelvic floor. Instead of pushing downwards with the lungs, one pushes upwards with the thighs, in the following way:

The right thigh pushes the cecum's contents upward into the ascending colon. The left thigh squeezes and lifts the sigmoid colon, and opens the kink where it joins the rectum. Squatting also relaxes the puborectalis muscle to open the outlet valve.

A conventional toilet defeats the purpose of this ingenious design. Trying to evacuate while sitting is like trying to drive a car without releasing the parking brake. In frustration, one pushes down forcefully  depressing the pelvic floor many times each day. Over the years, the pelvic floor gradually descends more and more, and stretches the pudendal nerve beyond its capacity.

How Pudendal Nerve Damage Causes Disease

Damage to this nerve has serious consequences for pelvic health. The uterus and ovaries depend on continuous feedback from the brain to maintain proper hormonal balance. The pudendal nerve also supplies the electrical energy  the "life force"  on which all cellular activity depends.

Cut off from the source of energy and intelligence, the pelvic organs become dysfunctional and prone to disease. Cancer, endometriosis and uterine fibroids can be viewed as different forms of "dementia" on the cellular level.

Endometriosis provides a good illustration of how cells behave when they lose contact with the brain. In this disease, the cells lining the uterus wander off and attach themselves to other organs  much like an Alzheimer's patient who has forgotten where she lives.

"Endometriosis is a painful, chronic disease that affects 5.5 million women and girls in the USA and Canada, and millions more worldwide." (Endometriosis Association) It is the second leading reason for hysterectomies.

Why Women Are More Susceptible

Pelvic floor nerve stretch injury, the root cause of most pelvic disease, affects women more frequently than men. One reason is that the vaginal canal is a structural gap which is more vulnerable to the unique stress produced by the sitting toilet.

Repeated use of the Valsalva Maneuver will often force the uterus, the bladder, the rectum or the small intestine into this gap. These hernias are called, respectively, uterine prolapse, cystocele, rectocele (pronounced REK-tuh-seel), and enterocele (pronounced EN-tuh-ruh-seel). The term "pelvic organ prolapse" covers all of them.

Rhonda Kotarinos, MS, PT, is a renowned physical therapist who has trained physicians at Stanford Medical School in techniques for treating pelvic floor problems. In a recent lecture to members of the Interstitial Cystitis Network, she stated that long-term Valsalva voiding leads to pelvic organ prolapse.38

The risk of prolapse is even greater during childbirth, when the Valsalva Maneuver is employed with maximum force. Here again, the modern toilet is to blame, because it has alienated women from the birthing posture they were designed to use. As explained in the Pregnancy and Childbirth section, squatting fully opens the birth canal and virtually eliminates the need for the Valsalva Maneuver.

This is why women in the developing world are "relatively unaffected by pelvic floor problems"36 while the United States spends more than $10 billion each year on pelvic reconstructive surgery and $26 billion to treat urinary incontinence.36

The high rate of C-Sections is another consequence of using the wrong posture for delivery. Natural (vaginal) childbirth is feared because it is performed in an unnatural and dangerous way. 32% of US births in 2007 were by C-section.37

The View of Gynecologists

Most gynecologists are unaware of the importance of squatting for bodily functions. They believe that the female reproductive system is prone to ailments because it was "poorly designed." In medical school, they are taught that the pelvic floor was designed for quadrupeds and cannot support the pelvic organs of women who walk on two legs. They are saying, in other words, that nature is incompetent.

But their theory ignores the fact that the pelvic floor has performed quite adequately throughout human history, with only rare exceptions. It is only recently, in modern westernized countries, that pelvic organ prolapse has reached epidemic proportions. In the developing world, among squatting populations, these disorders are quite rare.

Prolapse appears to be comparatively uncommon in much of the developing world, despite the much greater multiparity of its mothers ...34 [Multiparity means having many children.]

This evidence has baffled western doctors, since it contradicts their assumption that the pelvic floor is unsuited for bipeds. Their usual response is to claim that the problem is simply "underdiagnosed." Like the quadrupedal theory itself, this claim is asserted without any supporting evidence.

For example, the last quotation goes on to say, "It is uncertain if this is a real difference; [women in the developing world] may merely complain less."

But these women have to perform strenuous physical labor, just to survive. Daily chores include carrying buckets of water, tilling the fields, and washing clothes by hand. Pelvic hernias would make them virtual invalids.

If they do not "complain" it can only mean that they do not dislodge their pelvic organs by the habitual use of the Valsalva Maneuver. Furthermore, no amount of stoicism could conceal the presence of incontinence, the other major sign of pelvic floor dysfunction.

A Conflict of Interest

To test for rectoceles and other forms of prolapse, gynecologists ask their patients to perform the Valsalva Maneuver, which makes the prolapse bulge out. They are aware that excessive use of this maneuver can cause prolapse in the first place. But cultural insularity has made them view straining as unavoidable.

"Unavoidable" ailments mean job security, so gynecologists are quick to dismiss the possibility that "female troubles" can be prevented. Enormous amounts of money are at stake, creating an obvious conflict of interest.

The average cost for a hysterectomy ranges from $7,000 to $16,800 ... the annual cost for hysterectomies in the U.S. exceeds $5 billion.26

... the cost of surgical management of genital prolapse has surpassed $10 billion annually in the United States alone.36

Fortunately, a few gynecologists have a more enlightened perspective. Dr. Stuart Stanton and Dr. Ajay Rane were quoted above, strongly advocating the squatting posture for pelvic health. Other physicians have deplored the harm done by their colleagues in performing unnecessary surgery. Richard W. Te Linde (1894-1989) was the editor of the standard textbook on gynecological surgery. He is quoted in the Spring 2004 Whole Woman Newsletter:

...in the practice of gynecology, one has ample opportunity to observe countless women who have been advised to have hysterectomies without proper indications...I am inclined to believe that the greatest single factor in promoting unnecessary hysterectomy is a lack of understanding of gynecologic pathology...

A Case History

Dr. Akilah El, ND, PhD, is a naturopath with a deep understanding (and personal experience) of gynecologic pathology. In 1991, while still a student, she was diagnosed with cervical cancer and uterine fibroids. Ignoring the dire warnings of her gynecologist, she cured herself without the use of drugs, surgery or radiation.

A key factor in her recovery was the adoption of the squatting posture for elimination. This relieved the pressure on the pelvic floor and allowed the pudendal nerve to repair itself. In this way, the pelvic organs were reconnected to the central nervous system  the energy and intelligence that protects us from disease.

Dr. Akilah has repeatedly verified the effectiveness of this simple lifestyle change in helping her patients resolve gynecological ailments. The results have convinced her that "98% of all hysterectomies are unnecessary and dangerous." Dr. Akilah has summarized her program of self-cure in a tape called "Healing Our Womb - The Cause, Cure, and Prevention of Uterine Fibroids."

The previous section described how the habitual use of sitting toilets depresses the pelvic floor and causes a "stretch injury" to the pudendal nerve. This injury has many potential consequences  including incontinence, prostate dysfunction and chronic pelvic pain.

A recent article in the American Journal of Obstetrics and Gynecology (May, 2005) described another common result: female sexual dysfunction. According to the researchers, this problem affects up to 43% of women in the United States. Reuters Health issued the following report:

Nerve damage may underlie female sex dysfunction

By Anne Harding

Fri Jun 17, 2005

NEW YORK (Reuters Health) - Women with sexual dysfunction are more likely to have decreased tactile sensation in the genital area, according to researchers.

"Our data suggest that pudendal nerve impairment may play a role in sexual dysfunction in women," Dr. Kathleen Connell and colleagues write in the
American Journal of Obstetrics and Gynecology.

However, causes of this nerve abnormality remain unclear, Connell of Yale School of Medicine in New Haven, Connecticut told Reuters Health. "I think it's an area that we have to explore further because we don't have any good explanations. It's still sort of an enigma." ... [Full article]

The explanation given in the gynecological disorders section above should help the doctors solve their "enigma." Once they understand the cause of pelvic floor nerve stretch injury, they can give their patients practical advice on preventing it.

Even though the study only tested women, a man's pelvic floor is also vulnerable, as explained in the prostate disorders section. Nerve damage is the most likely cause of male sexual dysfunction, as well.

Fortunately, damaged nerves can grow back when they are no longer subjected to daily abuse. By repairing the connection between the pelvis and the brain, one has a chance of regaining normal sexual function.

Virtually every physician and physiologist who has ever troubled to write on the subject agrees that squatting is the most natural and physiologically sound posture to use for evacuation. This is the conclusion of Professor Alexander Kira, of Cornell University's Center for Housing and Environmental Studies, who conducted a seven-year study of the design of the modern bathroom. His 1976 book, The Bathroom, contains numerous quotations from Western scientists who have deplored the use of the modern toilet.12

He quotes Dr. Henry L. Bockus, the author of the standard textbook, Gastro-Enterology:

... The ideal posture for [evacuation] is the squatting position, with the thighs flexed upon the abdomen. In this way the capacity of the abdominal cavity is greatly diminished and intra-abdominal pressure is increased, thus encouraging expulsion ...11

Dr. Alexander Kira cites an article in the journal American Anthropologist and draws the following conclusion:

We must bear in mind that while we regard the use of the water closet as natural, we represent only a relatively small percentage of the world's population, and a percentage that may be said, in an absolute sense, to be wrong, insofar as we have allowed civilization to interfere with our biological functioning.12

Dr. William Welles, the chiropractor referred to above, wrote an article entitled "The Hidden Crime of the Porcelain Throne." Here is a brief excerpt:

The design of the modern-day toilet was created with absolute disregard for the anatomy of the human body. On the conventional Western toilet, pressure is exerted inside the abdomen by pushing the diaphragm down in such a way as to push all the organs of the body downwards, causing them to sag (prolapsus), and creating dysfunction of the ileocecal valve. The abdominal muscles are left totally unsupported, as we have said, and the body suffers the consequences.

Dr. Leonard Williams states that the modern toilet effectively paralyzes the abdominal muscles. "These muscles are little enough exercised by sedentary man, but when seated on the ordinary everyday water closet, he could not exercise them even if he would." 2

For 150 years, the people of the Western World have been the unwitting subjects of an experiment. By an accident of Fate, they were forced to adopt sitting toilets, while the other two-thirds of the world (the "control group") continued to use the natural squatting position.22

The results of this experiment have been clear and unequivocal. The experimental group has suffered dramatically higher rates of intestinal and urological disorders. The following diseases are almost exclusively confined to the Western World: appendicitis, colon cancer, prostate disorders, diverticulosis, bladder incontinence, hemorrhoids, and inflammatory bowel disease.

But the results have been misinterpreted by researchers who were unaware that the experiment was even taking place. Western doctors have tried to blame these diseases on the "highly refined" western diet. Their attempts have consistently failed to show that diet is a significant factor. Conventional medical websites all tell the same story:

This is a disease of the Western World. We don't know what causes it, or why the developing world seems so strangely immune.

Medical researchers have been working diligently to solve these deadly mysteries, but they have made little progress. Due to their habit of studying diseases in isolation, they failed to notice a remarkable coincidence: Many different bowel, bladder and pelvic diseases  previously rare or unknown  suddenly became commonplace in the last half of the 19th century.

This simple observation would have alerted them to the presence of a common underlying factor. It would have prompted the obvious question: What suddenly changed in the daily habits of the population?

The obvious answer: They abandoned the squatting posture for bodily functions (including childbirth.) For each disease, the anatomical relevance of this change has been explained above. The relevance is confirmed by the absence of these disorders among squatting populations.

In conclusion, the porcelain throne has caused enormous amounts of needless suffering, and the annual waste of billions of dollars in health-care costs. Clearly, the time has come to reacquaint Western Man with his natural habits  and put this unfortunate experiment to an end.
